Eli Ben-Sasson, co-founder of Starknet, said concerns that Bitcoin’s protocol has become too ossified were one factor behind Zcash (ZEC)’s recent price surge. Although he expressed strong personal support for Bitcoin, Ben-Sasson said the crypto community’s concerns about the network’s rigidity were legitimate. He also said Bitcoin holders had contacted him directly to report shifting portions of their positions into ZEC, suggesting some investors are seeking alternative privacy-focused assets. Ben-Sasson did not describe Bitcoin’s perceived ossification as the sole reason for Zcash’s rise. Cointelegraph reported his comments on September 17.
